[R] varclus in Hmisc vs SAS PROC VARCLUS

[Darin A. England]

My impression is that varclus from the Hmisc library is very
convenient to use when you want to get an idea of the correlation
among predictor variables in a regression setting, but if you want
to perform cluster analysis in general, you may be better off using
a different function in R, such as hclust or kmeans.
